SPECIFICATION forming part of Letters Patent No. 604,856, dated May 31, 1898.

Application filed March 31,1897. Serial No. 630,188. (No model.)

To all whom it may concern:

Be it known that I, JONAS DENBY, a subject of the Queen of Great Britain, residing at Park road, Bingley, in the county of York, England, have invented a certain new and Improved .Stop Mechanism for Oombing-Machines, of which the following is a specification.

My invention relates to the kind of combing-machines known as Nobles combs, and has for its object theproduction of stop-motion mechanism whereby on the sliver failing, as by breakage or otherwise, the motion of said combs is automatically arrested, on which certain of the parts of my said improved mechanism assume such positions as to leave all entirely clear for the operative to repair the breach or otherwise put the fibers in order, while, further, when the machine is again put into action or started my said stop-motion mechanism is again adjusted automatically or made ready for detecting any subsequent failing of the sliver, as before, without requiring the operative to rearrange or readjust any of its several parts in any way. In order that my said invention may be readily understood and carried into effect, I have hereunto appended sheets of drawings illustrative thereof, to which by letters reference is made in the following description.

Figure lis front elevation of a sufficient portion of a combing-machine to illustrate theapplication thereto of my improved parts. Fig. 2 is a view of same as seen from above. Fig. 3 is a front elevation of certain parts of the machine'with my improved parts applied thereto, the same being drawn to an enlarged scale. Fig. 4 is a view of the upper parts shown by Fig. 3 andjas seen'from' above. Fig. 5 is a sectional side elevation on line A B of parts shown by Fig. 3. Fig. 6 is a sectional plan on line C D of parts shown by Fig. 5. Fig. 7 is a similar view to Fig. 3, but

' shows the upper parts of same only and that drawn to a stilllarger scale, while the several parts are shown in positions assumed, as hereinafter explained. Fig. 8 is a side elevation similar to Fig. 5,.but drawn to a larger. scale, and shows the parts in the positions assumed, as hereinafter described.

Figs. 9 and 10 are similar views to Figs. 5and 8, drawn to the samelseale asiisaid. Fig. 5, and are illustrative of an alternative arrangement of parts to that illustrated by the severalfigures hereinbefore referred to. Fig. 11 is a front elevation of certain of the parts shown by Figs. 9 and 10. Fig. 12 is a view of the parts shown by Fig. 11 as seen from above. Fig. 13 is a drawing in detail of a part hereinafter described.

Similar letters of reference indicate similar parts throughout the'several views.

, To attain the object of my invention, I make use of a lever a, arranged to be held against the pull or tension of a spring I) by a catchpiece 0, formed on another lever c, mounted to be in contact with it. The lever a on being released by the moving of the lever c is pulled or forced, by its spring b to come into contact with a projecting piece d, fixed on the rod 61, which is used for shifting the drivingbelt at such time from the fast pulley e to the loose pulley c by means of the belt-guide 01 Thus the motion of the machine, which is transmitted thereto through the shaft fin the well known manner, is arrested.

Whenthe machine is in motion or operab, as above described,while suitable connecting-rods h h (and th'e supplementary lever 7c when this is desired to be used, as shown by Figs. 3, 4, 5, 7, and 8, or, if not used, then said f rods h h are formed and arranged as shown by Figs. 9, 10, 11, and 12) are held, by detector-levers m m, resting on the slivers n 'n',from pulling 'or pressing said holding-catch g from contact with the lever c, (in the arrangement shown by Figs. 3 to 8 such actions are produced by the weight of the levers mm drawing these rods h h in a downward direction,

1 so that by their nuts 76 it they may act upon the lever is, by which means they may raise or tend to raise its arm is, which passes beneath the arm 9 of the holding-catch g, and in the arrangement shown by Figs. 9 to-l2 the weight of the levers mm effects similar results on the catch 9 by forcing the rods h h in an upward direction,.so that by the nuts h if, I

which are in this casebeneath the arm g, this a-rm g maybe raised,) so that all the parts are held against the pull of said spring b.

However, when one or other of the said slivers a or n fails then its respective detector-lever m or m descends by gravity and forces the catch 9 from contact with the lever 0. Thus the spring Z) is permitted to pull the lever a over the somewhat-inchned catch-piece c and so bring along with the rod (1 by reason of coming into contact with its projecting part (1 and in this manner move the driving-belt by the fork or guide (Z from the fast pulley e to the loose pulley 0, thus arresting the motion of the machine, while when and as the said lever ais thus being moved by its spring Z) to stop the machine its said motion is employed for effecting a reverse or upward movement of the levers m m, so that these may be raised to be entirely clear of and above the path in which the slivers a a travel, so that perfect freedom is afforded for the operative to repair the failing or deficient part. The utilizing of this continued movement of the lever to for effecting said object, I am well aware, may be carried out in the varied ways by using well-known mechanical equivalents for those parts that I hereinafter describe. Still, however, as the following devices a11- swer their purposes efficiently the description of more complicated arrangements is unnecessary. In accordance with one of these arrangements I make the catch-piece c to actas an incline, so that as the lever to continues to move under it it causes the lever c to rise, as shown by Figs.7 and 8, sufficiently to bring its projection 0 into contact with the lever 7a, lifting this latter to bring with it the rods 7L 7L, (by coming into contact with the nuts 7L 7L3 above it,) and consequently also the levers m m, into the position shown by Fig. 8, in which they are entirely clear of the slivers a a, as desired. On the operative having repaired the wanting or damaged sliver by restarting the machine in the usual manner, which is by moving the rod (1, through the medium of the handle (1", in the opposite direction to that which the spring Z) had drawn it, the piece (1 will come into contact with the lever a, forcing it back against the pull of the spring 1) until it is clear of the inclined holding-catch c, on which the lever c is permitted to descend by gravity, and as it then is clear of the catch 9 this latter descends by the actions of its weighted arm 9, so that it again lays hold of said lever 0. During the descending of the lever 0 into this position its projection 0 will descend from holding the lever 7;. Consequently this lever 7.1, as also the rods 7L 71. and therefore the levers m m, will descend into their normal operating positions in contact with the slivers, where they will remain until another stoppage is effected by the failing of the said slivers.

The operating of the rod (1 by the handle (1 after the parts forming the stop-mo tion mechanism are readjusted, as above described,does

not interfere with said mechanism or move any part of it in any way.

In accordance with other arrangements I do not utilize the lever e for causing the levers m m to return to their elevated position; but instead of this I mount the lever 12 upon any suitable bearings, so that its weighted arm 1) when free may rest upon the arm 9' of the holding-catch g and cause it by its said weight to descend and press the rods 7t it (through the medium of the nuts 7L2 7t beneath the arm g) to raise the leversm m, as shown by Fig. 10. The liberating of the lever 19 to enable it to act in this manner is effected by the moving of the rod (Z to bring its projection 3 clear of the upward]y-extending arm of the said lever 19, and such moi ement of the rod (Z is in the direction for bringing the beltguide (1 to carry the belt from the fast to the loose pulley to stop the machines motion on the spring I) being liberated to act by the breakage or failing of the sliver, as above (lescribed.

It will be seen thatinstead of using the incline c in combination with the lever c in the arrangement first before described I may employ a lever similar to the lever 17 by arranging it to be operated by the lever a, or, again, this incline 0 may be used instead of the lever in the device last before described, in which case it would be secured to the rod d instead of the projection 5' being fixed thereon.

By arranging the rods h it so that they may be guided by slotted bearings 10, as shown by Figs. 5 and 8, I am enabled at any time to raise the levers m m out of their operating positions and clear of the slivers, as shown in broken lines, Fig. 8, or the same result may be obtained by having the rods h 7L slotted at their lower ends, as shown at 6, Figs. 9 and 10.

Such being the nature and object of my in vention, what I claim is- 1. In stop-motion mechanism for combingmachines, the combination with spring-actuated belt-shifting mechanism having a detent for holding it against the action of its spring, of detector-levers adapted to rest on the slivers, connections between said levers and detent whereby the descent of either or both of the levers will release the said detent, and means whereby the lovers may be independently moved to inoperative positions.

2. In stop-motion mechanism for combingmachines, the combination with spring-actuated belt-shifting mechanism, of a lever havin g a detent for holding said mechanism against the action of its spring, said detent having an inclined side, detector-levers adapted to rest on the slivers, rods connected with the detector-levers and having connections whereby they will release the detent 011 the descent of one of the detector-levers, and means operated by the spring-actuated movement of the belt-shifter to ride under the inclined side of the detent and elevate its lever and also the rods and the detector-levers.
